WVHIFFLETBEE-HOOK.

Application filed September 24, 1914.

To all 1 .7mm it may concern Be it known'that I, GEORGE H. GRTFF, a.citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Whiflletree-Hooks, of which the following is a specification.

This invention relates to hooks for making the connection of the tracesof a harness with the whiiiietree, and its object is to provide asimple, efficient and strong hook of this kind. together with animproved guard for the hook whereby the traces are prevented from beingaccidentally disconnected, said guard being easily manipulated toconnect or disconnect the traces.

With these objects in view, the invention consists in a combination andarrangement of parts to be hereinafter described and claimed, referencebeing had to the accompanying drawing, in which Figure l is a plan viewof the device; Fig. 2 is an end view thereof, and Fig. 3 is alongitudinal section on the line 33 of Fig. 1.

Referring specifically to the drawing. 5 denotes a ferrule having a hook6 on one side, the hook being preferably formed integral with theferrule. The inner end of the ferrule is open so that it may he slippedover the end of the whiifletree 7 to which latter it is made fast by across pin 8.

The outer end of the ferrule 5 is closed, as indicated at 9, and fromsaid end extends a stem 10 which is angular in cross section. On thisstem is slidably mounted a sleeve 11,

the inner end of which is closed, as indicatedat 12. and normally seatson the outer end 9 of the ferrule. As the stem is angular incross-section, the sleeve is prevented from rotating thereon, it beinghowever free to slide. The outer end of the stem carries an abutment 13in the shape of a disk of such diameter as to seat in the outer end ofthe sleeve. fiush therewith. A spring 1-1 is coiled around the stem,between the abutment 13 and the inner closedend 12 of the sleeve.

The sleeve 11 carries a guard 15 for the hook 6, said guard being in theshape of a finger which projects outward from the side of the sleeve soas to extend to the tip of the bill of the hook, said tip having agroove 16. The tip of the guard finger is beveled, as indicated at 17 toseat in the groove 16.

The hook 6 extends from the ferrule 5 and terminates in a curve towardthe side of the Specification of Letters Patent.

sleeve 11, from which latter the tip or extremity of the hook is spaced,and across which space the guard finger 15 normally extends, thusclosing up the hook and preventing the trace ring held by said hook fromaccidentally slipping off the same. The finger is held in this positionby the spring 1 1. To apply or remove the trace ring from the hook, itis necessary only to pull the sleeve outward, as shown dotted in Fig. 1,which takes the guard finger away from the hook and leaves the sameopen. The disk 13 closes the outer end of the sleeve 11, and the spring14 is therefore completely housed and protected. As the engagement anddisengagement of the guard finger is effected by a longitudinal slidingmovement of the sleeve, and not by a turning movement. the liability ofbreakage of the spring is reduced to a minimum.

The device is easy to operate and its construction also enables it to beused at either end of the whiiiletree.

I claim:

1. A wh'illletree hook comprising a ferrule, a. hook extendingtherefrom, a stem projecting from the outer end of the ferrule, a sleeveslidably and non-rotatably mounted on the stem, said sleeve beingslidable outward from the end of the ferrule, the tip of the aforesaidhook pointing toward the side of the sleeve and being spaced therefrom,a guard finger proiecting from the side of the sleeve and extending tothe tip of the hook, and a spring restraining movement of the sleeve ina direction outward from the end of the ferrule to carry the guardfinger away from the tip of the hook.

2. A whifiletree hook comprising a ferrule which is closed at its outerend, a hook extending from the ferrule, a stem projecting from the outerend of the ferrule, a sleeve slidably and non-rotatably mounted on thestem, said sleeve being slidable outward from the end of the ferrule.the inner end of the sleeve being closed and seating against the outerend of the ferrule, and the tip of the aforesaid hook pointing towardthe side of the sleeve and being spaced therefrom. a guard fingerprojecting from the side of the sleeve and extending to the tip of thehook, an abutment on the outer end of the stem, said abutment closingthe outer end of the sleeve, and a spring in the sleeve between itsclosed inner end and the abutment.

8. A whiifletree hook comprising a ferrule,

a hook extending therefrom, a stem projecting from the outer end of theferrule, a sleeve slidably and non-rotatably mounted on the stem, saidsleeve being slidable out- Ward from the end of the ferrule, the tip ofthe aforesaid hook pointing toward the side or" the sleeve and beingspaced therefrom, a guard finger projecting from the side of the sleeveand extending to the tip of the hook, said tip 01 the hook having agroove and the tip of the guard finger having a bevel to seat in saidgroove, and a spring restraining movement of the sleeve in a directionoutward from the end of the ferrule to carry the guard finger away fromthe tip of the 15 hook.

In testimony whereof I afiix my signature in presence of two Witnesses.
